CLOCK-RESONATOR.

SPECIFICATION forming part of Letters Patent No. 557,040, dated March24, 1896.

Application filed February 4, 1895. Serial No. 537,280. (No model.)

To all whom t may concern.-

Beit known that I, STEPHEN WILLcoCK, of the city of Toronto, inthecounty of York and Province of Ontario, Canada, have invented a certainnew and useful Resonator for Striking and Chime Clocks, of which thefollowing is a speciiication.

The object of my invention is to devise means for increasing the volumeand improving the quality of the sound from the gongs or bells of astriking or chime clock; and it consists, essentially, of aresonating-chamber, preferably located at the bottom of the clockcaseand provided with curved deflectors to throw the sound out through aseries of holes in one of the walls of the chamber, the standardcarrying the gong or bell being rigidly connected to either the upper orlower soundboard of the said chamber, the whole being arranged in detailsubstantially as hereinafter more specifically described and thendefinitely claimed.

The drawing is a perspective view, partially broken away, showing myimprovements applied to an ordinary striking clock.

A is a portion of the case of a clock.

B is a resonating-chamber, preferably located at the bottom of theclock-case. This chamber is formed by the side walls C D E F and theupper andv lower vibratile wallsA or sound-boards G H, which arepreferably made of spruce or other suitable resonant material.

I is a standard supporting the weight J, to which is connected the gongK. This standard is preferably bent, as shown at a, and after passingthrough the hole b in the upper sound-board G is rigidly bolted orotherwise secured to the lower sound-board H, as shown.

L are two curved deiiectors, the ends of which are connected,respectively, to the walls E and F of the resonating-chamber. Thesedelectors being yquite independent of the soundboards G and II do not inany wise affect their vibrations.

M are a series of holes formed in the wall F to permit of the escape ofthe sound from the interior of the resonating-chamber. From thisconstruction it follows that the vibrations of the gong K are conveyedthrough the standard I to the soundboard H, throwing it into vibration,and with it the air contained inthe `in some clocks to adapt theposition of the gong to the position of the striking-hammer. It is notessential that both the boards G and H should be of a vibratile orresonant material, as one will in many cases answer the purposes of myinvention, nor is it essential when both the boards G and H areconstructed of such material that the standard I should be connected tothe lower, as substantially the same results will be obtained bysecuring it to the upper sound-board G. The resonant chamber might alsobe placed at the side of the clock-case, but I consider the positionshown as preferable. lVhen my resonator is used with a clock, theimprovement in the quant-ity and quality of the tone of the gong overthat produced by a gong carried in the usual way is very marked. Thisimprovement is specially noticeable in chime-clocks, to which myresonator is consequently a valuable adjunct.

Of course other mechanism might be used to take the place of the gong orbell producing the vibrations to be amplified by the resonating-chamber.

That I claim as my invention isl. In a striking or chime clock, aresonating-chamber having a sound-outlet and a vibratile wall, a gong, aweight on which said gong is carried, and a standard carrying saidWeight and mounted on said vibratile Wall and transmitting motion to itfrom the gong, substantially as described.

2. In a striking or chime clock, a resonating-chamber provided with asound-outlet and having two vibratile walls or soundingboards, incombination with a standard forming a support for a gong, said standardpassing through one of said vibratile walls and connected t0 the othervibratile wall, substantially as described.

3. In a striking or chime clock, a resonating-chamber provided with asound-outlet and IOO having a vibratile Wall or sound-board, incombination With a bent stand ard rigidly connected to the center of thesaid vibratile Wall, a Weight carried by the said standard and a gongcarried by the said Weight, substantially as and for the purposespeciiied.

4. In a striking or chime clock, a resonatingchamber having a vibratileWall or soundboard, to which a gong or bell is connected, in combinationwith deectors suitably held between the said vibratile Wall and the Wallopposite thereto, and a suitable outlet in one of the side Walls of thechamber toward Which the said deiiectors direct the sound, substantiallyas and for the purpose specified,

5. In a striking or chime clock, a resonating-chainber comprising theside walls C, D, E, F, and the vibratile Walls or sound-boards G, Il, toone of which is rigidly connected the bell or gong K, in combinationWith the curved deectors L, connected to the side Walls E, F, one ofwhich is provided With suitable soundoutlets, substantially as and forthe purpose specified.

6. In a striking or chime'clock, a resonating-chainber comprising theside Walls C, D, E, F, and the vibratile Walls or Sound-boards Gr, H, incombination with the standard I, the Weight J, the gong K, and thecurved deflectors L, connected to the side Walls E, F, the Wall F beingprovided With a series of holes M, substantially as and for the purposespeciiied.

7. In a striking or chime clock, the combination of the side Walls C, D,E, F, the soundboard G, having a hole therein, the soundboard H, thebent standard I, passing through the hole b, and rigidly secured to thesoundboard I-I, the Weight J, the gong K, and the curved defiectors L,connected to the side Walls E, F, the latter Wall being provided with aseries of holes M, substantially as and for the purpose speciiied.
